DS is 15, currently has one more week of study leave but doesn't have any more exams. Find him really hard to talk to without him becoming defensive. He's got friends and a girlfriend, but spends a lot of time in his room on his X Box. I want to make sure he's out and doing at lesat one thing every day, but he's so stubborn he just refuses if i suggest something. We get on well, but this is hard. Any suggestions about how to make this work?
